Title: Double-seated valve
Inventor: OTANI HIDEO
IPC: F16K27/02
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To suppress intensive collision of fluid against a valve casing wall part so as to reduce vibration by partitioning the inside of the valve casing into a primary side flow passage and a secondary flow passage and forming a partition wall dividing the secondary side flow passage into the upper and lower side flow passages so that the end wall part on the outflow port side can be seen from the outflow port. SOLUTION: When a plug 6 is lifted so as to open a valve, fluid flowing into a primary side flow passage 20 from an inflow port 2 is divided into the upward fluid heading toward an upper flow passage 30a and downward fluid heading toward a lower flow passage 30b, and then, the divided flow converges in an outflow port 3 so as to be discharged from the outflow port 3. In a double-seat valve constructed in this way, a partition wall 4, which divides the inside of a valve casing 1 into a primary side flow passage 20 and a secondary side flow passage 30 and divides the secondary side flow passage 30 into the upper flow passage 30a and the lower side flow passage 30b converging together in the outflow port 3, is formed so that an upper side 40a of an end wall part 40 on the outflow port 3 side can be seen from the outflow port 3 side.  In this way, fluid collision against the wall part of the valve casing 1 is reduced, so that vibration in an operation device system can be lowered.

Title: Molding machine and replacing method for chase block used therefor
Inventor: SUZUKI JUNICHI
IPC: B29C45/26
Filed: 1994-09-08
Abstract: PURPOSE: To increase the clearance between a chase block and a movable block at the time of replacing and to facilitate the replacement by moving on a die set at the time of replacing the chase block and moving the movable block for pressing to the reference surface of a center block to be fixed at the time of fixing by moving means. CONSTITUTION: At the time of replacing a chase block, a movable block 7 which presses a chase block 4 by an air cylinder 8 is moved in a direction for separating from the block 4. Since the block 7 is installed in the state that a fixed block 7a mounted at the chase block installing surface 3a of a die set 3 is held, the block 7 is smoothly moved on the surface 3a, and a clearance between the block 4 and the block 7 is increased, and hence the chase block can be easily taken out. At the time of mounting a new chase block 4, the block 4 is pressed to a stopper block and the reference surface 5b of a center block 5.

Abstract: PURPOSE:To automatically correct a reference bearing to a bearing corresponding to the direction of a working process of a working car and to remove the interruption of working by changing the reference bearing by prescribed angle in the operating direction in case of repeating operation in the same direction by a manual steering means. CONSTITUTION:The direction of the machine body of an automatic traveling working car is detected by a bearing sensor 8 fitted to the machine body and steering operation is automatically executed by a bearing control means 100 based on the detecting information of the sensor 8 so that the machine body 1 is traveled in the previously set reference bearing (alpha). A manual steering means 101 in the means 100 executes steering operation with priority. When steering operation in the same direction is repeated by the means 101, the reference bearing (alpha) is changed by a prescribed angle (DELTAalpha) in the direction of the steering operation by a reference bearing changing means 102. Thus, the reference bearing is automatically corrected in the bearing corresponding to the working process by said changing operation to remove the interruption of working.
